Azjol Nerub is a dungeon in the World of Warcraft game. The level range for the normal dungeon is 69-74. The main anagonist race in this dungeon are Nerubian. The location of the entrance to Azjol Nerub is in the Dragonblight zone on the continent of Northrend. The instance was released in the Wrath of the Lich King expansion. The dungeon contains 3 bosses. The end boss of Azjol Nerub is Anub`Arak.
Ajzol Nerub along with the Ahn'kahet, the Old Kingdom are to be found underground, there is a path and a holes in the ground that will take you to the dungeon. The difference between the two dungeons, is one you need to go down a slope to get to but this one is at the same level as the summoning stone. All the bosses in Ajzol Nerub are Nerubian Spiders.
The area where the dungeons are located is a labyrinth of cave, it is best to locate the dungeon by dropping through the ceiling which is further on from the ground level dungeon.
Krik'thir the Gatewatcher is the first Nerubian you will meet, you should be careful of him as he can fear people. The achievement for Krik'thir involves killing the boss without killing the lieutenants, quite easy at high level, fun when you're level 80.
The second boss Hadronox appears off screen, if you're high enough, you should aim to take out Hadronox before he has a chance to move into the main arena. After that boss, there's only one left and its a bit of a drop to get to him. DOn't worry about the fall, you land in water to soften the blow. Once you clamber out, you can ignore the small spiders and move through until you see some bigger spiders. The bigger spiders must be killed before the final boss.
The final boss is Anub'arak who all the players should make sure that they are in the arena before you start as the walls go up to prevent anyone getting in or out. Anub'arak will occassionally bury himself under ground and spear the ground, hitting people. Whilst he's under ground, you need to make sure you don't get speared.
